tests: account for different newline behavior between Solaris and GNU grep GNU grep, when emitting a matching line that doesn't have a terminating newline, will add an extra newline. Solaris grep passes the original line through without the newline. This causes differences in test output when looking at the last line of the output of get-with-headers.py, which doesn't usually emit (and certainly doesn't guarantee) a terminating newline. Both grep implementations succeed in matching the requested pattern, though, so rely on specifying the full pattern on grep's commandline instead of expecting it in the output, and send the output to /dev/null.

tests: also allow "Protocol not supported" in test-http-proxy error I've seen this in a (misconfigured) FreeBSD jail which has ::1 as an entry for localhost, but IPv6 support is disabled in the jail. It took me months to figure out what was going on (and I only figured it out when tinyproxy.py got confused by similar IPv4-level misconfiguration of the localhost domain in /etc/hosts.) I don't feel strongly about this patch: on the one hand, it's papering over a host-level misconfiguration, but on the other it avoids some weird and hard to diagnose problems that can occur in weirdly restricted environments.

revset: prevent using outgoing() and remote() in hgweb session (BC) outgoing() and remote() may stall for long due to network I/O, which seems unsafe per definition, "whether a predicate is safe for DoS attack." But I'm not 100% sure about this. If our concern isn't elapsed time but CPU resource, these predicates are considered safe. Perhaps that would be up to the web/application server configuration? Anyway, outgoing() and remote() wouldn't be useful in hgweb, so I think it's okay to ban them.

tests: use an absolute path to get around '..' being invalid on a dead CWD Only FreeBSD seems to be this picky. Note that this explicit absolute-path `cd` exposes a defect in the test, in that we end up still inside the cwd-vanish repository, but that's not a regression in this change. Since we're in a code freeze, I'm doing the smallest thing possible to try and fix bugs on FreeBSD, rather than cleaning up the entire problem. I'll follow up with a more complete fix after the freeze.

ui: rename tmpdir parameter to more specific repopath This was requested by Augie and I agree that repopath is more descriptive.

pager: wrap _runcommand() no matter if stdout is redirected We've made chg utilize the common code path implemented in pager.py (by 815e1cefd082 and 493935e0327a), but the chg server does not always start with a tty. Because of this, uisetup() of the pager extension could be skipped on the chg server. Kudos given to Sean Farley for dogfooding new chg and spotting this problem.

shelve: make unshelve not crash when there are missing files (issue4176) This patch makes it possible to unshelve while having missing files in your repo as long as shelved changes don't touch those missing files. It also makes error message better otherwise.

statprof: require input file statprof has a __main__ handler that allows viewing of previously written data files. As Yuya pointed out during review, f42cd5434cc2 broke this. This patch fixes that.

tests: work around FreeBSD's unzip having slightly different output According to man 1 unzip, this unzip appeared in FreeBSD 8.0. It's what comes as /usr/bin/unzip, so we may as well cater to it since it's easy.

contrib: fix check-commit to not reject commits from `hg sign` and `hg tag` I'm tired of having a spurious red build every time we do a release. Fix it once and for all.
